Sometimes during commute, there are some things that can be put together quickly along with images, so ideally, everything can be created within discourse and save to draft. When trying to create another topic, only the previous one is shown.
Since there isn’t a draft feature (like wordpress posts) that can be used to start multiple topics (ideas + images + formatting) and prepare it for publishing, any tips and how to handle this?
You could set up a “Draft Topics” private category. Then move the topic to the public category when ready.
Moving a topic to a new category won’t generate an email/notification for users watching/tracking that category, so you would want to copy/paste the content if you want to trigger an email/notification. (I believe this is correct but you can test it.)
Another “hacky” way to do it would be to create a low-trust account (TL0), post the new topic from that account and then approve it from an admin or moderator account at a later time.
Write a private message to yourself
Thanks for all the suggestions! Will give them a try.
@riking Never thought to private message. Will I be able to then just publish as a regular post or will I need to cut and paste into a new post?
If you have replies in mind, there is a drafts section on your user profile now so they are much easier to find. You can have as many reply drafts in flight as you like.
However, if you wish to create multiple new topics, you’ll still need to send yourself private messages as @riking mentioned; at the moment, only one new topic draft is supported, still.
Is there any plan to support multiple draft topics?
Additionally, for staff this pattern has been formalized in the Shared Drafts feature!
여러 개의 초안을 플러그인으로 지원할 수 있는지에 대해 생각해 본 사람이 있습니까?
해킹 같은 우회적 방법을 쓰지 않고도 여러 개의 게시글 초안을 작성해 두고, 나중에 특정 시점에 게시하도록 예약할 수 있는 기능은 정말로 가치 있다고 생각합니다…
게시물 예약을 찾고 계신다면, 공유 초안 기능을 확인해 보세요.
그렇게 하면 될 것 같네요. 한번 시도해볼게요 
여러 초안을 작성할 수 있는 기능이 로드맵에 있나요? 말씀하신 방법들은 모두 좋은 대안이지만, 여러 게시물을 동시에 작업할 수 있는 내장된 “초안” 탭이 있으면 정말 좋겠어요 
참고로, 게시물을 올린 카테고리를 '관심’이나 '첫 게시물 관심’으로 설정한 사용자가 있다면, 해당 사용자에게 알림이 전송되고 해당 주제에 대한 직접 링크가 제공됩니다. 따라서 생각만큼 은밀하지 않을 수 있습니다.
